File Encryptor/Decryptor [Vega / 1superchip] - Vega - 08-29-2020 File Encryptor/Decryptor [Vega / 1superchip] For Wii Console use only. No Dolphin, no Wii U. This code will allow you to choose a file on your nand to either encrypt or decrypt it using Starlet's AES engine. The original file WILL BE REPLACED with the encrypted/decrypted version. Simply fill out all the values below and run the code. When you launch MKW, there will be a brief moment (visual glitches may occur) until you are returned to the Wii's Main Menu. The code has been executed and the file has been encrypted/decrypted. NOTE: You need full hardware rights. Guide -> https://mkwii.com/showthread.php?tid=1596 Also, this code makes use of memory addresses 0x800007C0 thru 0x800007C3. Make sure no other codes you have equipped are using those addresses. X = Encrypt or Decrypt 0 = Encrypt 1 = Decrypt K = Your Key (in Hex) V = Your IV (in Hex) Z = Filepath (Use any online ASCII to Hex converter for assistance) NTSC-U C20095F4 00000042 3AE0000X 48000065
